Well, I don't like Tamers that much... I mean, yes, I like it, but it's my least favourite of the 3 I've watched ^^
I haven't seen 04 and 05.
I used to not think very highly of 02, but ever since I saw it in japanese (and discovered how much it was ruined by americans [no offence to american people here]), it became my favourite. I swear, it's really different. I could go on a 3 pages rant about how they changed the dialogues to make the characters sound stupid, and all the "violence" that was edited, making the story lose its deepness, but I don't think you need that ;)
